AI Technical Summary

Technical Problem

Existing batch reactors suffer from problems such as large backmixing, numerous side reactions, significant loss of volatile materials, low heat exchange efficiency, large equipment size, and long production time, resulting in low VC synthesis efficiency and high production costs.

Method used

The tubular reactor, combined with a static mixer and a gas-liquid separator, forms a piston flow within the pipeline. Through spiral or S-shaped pipeline design, combined with hot water heating and condensation reflux, continuous production is achieved, reducing backmixing and volatilization losses.

Benefits of technology

It achieves shorter reaction time, fewer side reactions, lower loss of volatile materials, smaller equipment footprint, continuous production, high operational stability, and reduced analysis frequency and equipment investment.
